contraction process的用法和樣例：
例句
- Each of the troponin complexes appears to determine the ability of seven actin monomers to participate in the contractile process.
每個肌鈣蛋白複合物決定著七個肌動蛋白單體參加收縮過程的能力。 - As contraction continues and the density increases, the dust becomes so thick at the center of the cloud that it absorbs the far-infrared radiation.
當收縮過程繼續進行下去，密度不斷增大時，氣塵雲中心的塵埃就會變得極其濃密，因而能夠吸收遠紅外輻射。
